The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

New products and practices take time to diffuse, a fact that is often attributed to some form of heterogeneity among potential adopters. People may realize different benefits and costs from the innovation, or have different beliefs about its benefits and costs, hear about it at different times, or delay in acting on their information. This paper analyzes the dynamics arising from different sour...

This paper extends the literature on technology adoption by introducing a distinction between technological breakthroughs (‘innovations’) and the engineering re/nements (‘improvements’) that follow such a breakthrough. Firms do not necessarily wait for a future technological breakthrough, but instead have an incentive to delay the adoption of a new technology until it is su2ciently advanced. We...

Using 1985–1999 data from the German Socio-Economic Panel Study (GSOEP) to analyze wages we confirm the hypothesis that existing computer wage premiums are determined by individual ability or other unobserved individual characteristics rather than by productivity effects. While a rather large personal computer (PC) wage premium was found in the crosssectional regressions even after the inclusio...
